COMBINED SHUTTER-WORKER AND SLAT-OPERATOR.

SPECIFICATION forming part of Letters Patent No. 312,300, dated February 17, 1885.

Appication fied March 15, 1884. (X0 lllOtlul.)

To whom it may concern.-

Be it known that I, THOMAS H. SMITH, of Auburn, Cayuga county, New York, have invented certain new and useful Improvements in Devices forOperating and Locking Shutters; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of rcferencemarked thereon, which form partof this specification, in which Figure 1 is a front view of the window or door frame, and of the shutter closed and locked by my invention. Fig. 2 shows a side elevation of the same, with sectional view of the window or door frame. Fig. 3 shows a side view of the same,with the shutter locked in its open position. Fig. 4t shows the parts in the same position as in Fig. 3, looking against the edge of the opened shutter. Fig. 5 shows the face of the actuatinggcar detached from the other parts, and Fig. 6 shows the horizontalgear detached as seen from below.

This invention relates to devices for operating and locking shutters from the inside of an apartment, and which may have the further capacity of operating and locking the slats of the shutter; and it consists in the construction, arrangement, and combination of certain parts, as hereinafter specified, by means of which these results are accomplished.

A represents a window or door frame, and B is a shutter, adapted for closing the opening through the frame, which shutter is supported either by the usual hinges, or my device may serve in place of either hinge, as in addition to its other functions it possesses that of a hinge.

0 represents a toothed segment,having a series of cogs upon its under horizontal surface, as shown. This segment is made with the flange-plates eand f, for securing it to the shutter, a post or pintle, d, which serves asahinge upon which the shutter turns, and which is held down to its proper position by a pin, g, inserted through it. It also has the lockingteeth h and i, for the purposes hereinafter de scribed. A lever, K, is pivoted at n, and bears at'its extremity 0 a connecting-rod, p, which is attached at its other end to the movable slats of the shutter or to the rod which connects said slats, andthereby actuates them as the lever K is made to rock upon its pivot a. The other end of the lever K takes into a mortise in the plate H when the slats are closed, and thereby furnishes a secondary locking device for the shutters. The segment aforesaid covers the cogs upon its horizontal surface and protects them from injury, ice, or other foreign matter from above. A handle, R, is furnished with a hollow spindle, s,whieh extends into the window or door frame, and clasps a square spindle, t, which bears upon its other end the actuating and locking gear V upon the outside of said frame. The handleR may be of any convenient shape; but for the purposes of my invention, and in order to secure chcapness of construction, I cast it of metal solid with its spindle s. The spindle s has a doubled iron wire cast init and projecting laterally from it, as shown at to, which is capable of passing through the slot :0 in the plate y, after which it is'spread apart, and thereby prevented from returning through said slot, and the plate y being secured by screws to the frame,the handle It is retained in position. The combination of the spindles s and t,

as described, gives a capacity of adaptation of my device to any desired thickness of window or door frame. The gear V is furnished with radial cogs for about two hundred and twenty degrees of its cirenmferen ce, andthe remainder of its circumference bears the locking-lug F, which takes against the locking-teeth hand t, and thereby locks the shutter in its open or closed position. Apin,z, projects beyond the circumference of the gear V and serves to actuate the lever K. A plate, H, is secured by screws to the outside of the door or window frame, and supplies a bearing for the hinge post or pintle d, the spindlet passingthrough it. A mortise in the plate H receives the extremity r of the lever K when the shutterslats are closed.

The operation of my device is as follows: By grasping and turning the handleR thegear V is rotated, and its cogs meshing with the cogs of the toothed segment 0, the segment is turned upon its axis (1, and theshutter is carried from "its open to its closed position, or vice versa. As the toothed segment reaches the end of its rotation the solid lug F takes against the teeth h and 1', respectively, and thereby locks the shutter in either of its changed positions. I It is apparent from the construction of the parts that when the shutter is closed and the parts in the position shown in Fig. 1, a rotation of the gear V of less extent than will suflice to clear the lug F from the locking tooth h will actuate the lever K by means of the pin z, thereby opening or closing the slats of the shutter without unlocking said shutter.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
